Common Green Darner

<em>Anax junius</em>, commonly known as the common green darner, is a large dragonfly belonging to the genus Anax within the family Aeshnidae. This species occupies virtually all terrestrial and freshwater habitats, and its range is centered on the United States, where it is one of the most recognizable and widespread dragonfly species. Common green darner is assessed as Least Concern on the IUCN Red List. The species is well known for undertaking long-distance migrations, with populations moving southward in autumn and northward in spring across North America. Adults are typically found near ponds, lakes, and slow-moving streams where females deposit eggs in aquatic vegetation. Biological traits of this species remain poorly documented in the scientific literature.

Bely Medved

The largest land carnivore on Earth, polar bears can exceed 700 kg and are found across Arctic sea ice from Canada to Russia. Highly specialized marine mammals that rely on sea ice to hunt ringed and bearded seals. Excellent swimmers capable of covering vast distances in open water. Listed as Vulnerable, with populations under severe pressure from rapid Arctic sea ice loss due to climate change.
